IMPROVEMENT 1N HORSE HAY-RAKEsf Specification forming part of Letters Patent No. 26,294, dated November 2f) 185() lb all whom 'it may concern: i

Be it known that I, MATHrAs RAEZER, of Reading, in the county of Berks and State of i Pennsylvania, have invented certain new and longitudinal section on line a' w of Fig. l; and

Fig. 4 is a transverse section,.showing the application of the spring foot-lever and catch for controlling the rake.

The same letters of reference denote like parts in each figure.

To enable others skilled in the art to make and use my invention, I will proceed to describe it with reference tothe drawings.

In the said drawings, Ais the main frame or platform of the machine; B B,the bearingwheels; C, the axle of said bearing-wheels. E is the drivers seat, supported from platform A by the spring E. Gr G are the shafts, to which the horse is attached; H, the sin gle-tree which is attached to the sliding bar I, which bar is moved back and forth through the guides I'. This bar I is connected by the link I" to the arm M on the rock-shaft N, said 4rock-shaft serving as the rake-head, and to which the rake-teeth c are applied in any usual or well-known manner of applying such teeth. These teeth pass through the enlarged parts or heads of the pins e. Said pins pass through a spring-bar, F, and slide freely therein. Spiral springs d are placed on the pins d, between the spring-bar and the heads e of the pins, which springs bear the teeth against the ground with a yielding pressure. A greater degree of elasticity is given to this yielding i pressure ofthe teeth upon the ground by means of the springs g on pins f. These pins pass through brace-guides L, which are attached to the rock-shaft on the rake-head N.

To each end ofthe rake-head N segment or part pinions N are` applied, the teeth b of which mesh with the teeth a of similar segments 0' on the rock-shaft O. Said rock-shaft `O is provided with the clearers P, which pass between the teeth of the rake, and serve,lwhen Vthe rake is thrown up, to clearthe grass from the teeth.

J is a hand-lever, which is pivoted to the' standards R on the main frame. The short arm of said lever is in the form of a segment,

and is furnished with the teeth fifi, Whichteeth mesh into the teeth h of the rack on bar I, and

through which motion is given to the said bar through the guides I. i

K is a springfootlever, which passes through the platform at K', and is bent as shown atj, Fig. 4, and is pivoted at k to the platform.

7c is a spring, which serves to hold the lever in position to retain the catch on thereon in` a notch or groove in the bar I, when said baris thrown back, so as to allow the teeth of the Y A rake to rest uponthe ground. l

The operation is as follows, vizi The draft` y from the notch in the bar I, when said bar is` drawn forward, and acts through the link I upon arm M ot' the rake-head N, causing the rake-head partially to revolve, thereby throwing up the rake-teeth, and at the same time, through the teeth a and b on the segments N and 0, the clearers I on the rock-shaft O are caused to move in an opposite direction, and

-thus to clear the grass from theteeth of the rake. This motion of the bar I, through the teeth h thereon and the teeth t on the short arm ofthe lever J, causes the long arm ofthe lever to bo thrown back in convenient position to be seized by the driver. The teeth of the rake being now cleared, the driver forces l forward the lever J, thereby bringing the bar again into thepositiou shown in Fig. 3, where it is again retained, as before, by the springcatch on the foot-lever, and the process is as before.

I have shown the bar `as resting upon the platform; but it is obvious that the said bar maybe placed underneath the platform Withdraft-bar I, when the several parts are aront in any way changing the character of the ranged and operated in the manner and for invention. a I the purpose described.

PagltIsalm, and desue to secure by Letters MATHIAS RAEZER.

The combination of the rock-shafts N and Vibnesses:

O, clearers P, teeth c, brace-guides L, spring- XVM. B. SCHOENER,
